Preparing the Fibre Optic Cable
Fitting the fibre optic cable into the AquaBAT or into the Header unit does not require any specialist
tooling or prior knowledge in the use of fibre optic cabling. In order to use it cut the cable to the correct
length, allowing a few metres of spare cable in case the ends become damaged, and strip the outer
sheathing away as specified for the instrumentation.
The fibre optic cable is constructed in 2 parts and consists of an outer protective sheath and an inner
plastic core. The outer sheath is 2.2 mm in diameter and the solid plastic core is 1 mm in diameter.
Cut the sheath away exposing the solid plastic inner core. Simple wire strippers are more than
adequate for this operation. When using the more expensive strippers set the stripping depth to no
less than 1 mm.

AquaBAT deployed at the Bottom Bore Hole / Stand-pipe
This is the simplest of the deployment options for the AquaBAT and it is simply a
matter of connecting the instrument to the fibre cable and deploying it down the bore
hole. Once the AquaBAT is at the bottom of the hole simply lock off the cable gland
and cut the fibre to suit the location. Fit several of the star washers to the cable above
the cable gland to prevent the cable end from slipping.
Alternatively, simply cut extra cable and terminate securely to the inside of the well
head or on the man hole. floor. Fit the plastic cap to the end of the fibre cable when
not in use to keep the cable head clean.
Clean the Fibre end before insertion into the Header interface. Simply run the fibre
under water or wipe with a cloth. Some moisture on the fibre when inserted into the
Header unit or AquaBAT will have no affect on its operation.
Fixed Level installation
This is the most common method of deployment for the AquaBAT.
For this type of deployment it is recommended that the fitting of a fixed position
deployment bar (see opposite) is used to take the strain of the instrument when it
is deployed, and to re-position the sensor should it be removed for maintenance.
A Carabeana is attached to the bar and the Fibre cable is wrapped around it a
number of times to prevent it slipping. The AquaBAT is deployed below the fixing
bar to its permanent position. So long as the cable gland is tightly fastened and the
star washers are attached to the excess cable then the sensor will be permanently
placed and the results will reliable.
No special care needs be taken to protect the fibre cable that protrudes from the
top of the bore hole cover. When not in use fit the protective plastic cap onto the
end of the cable.
Where possible and when long term deployment is going to be carried out leave
the excess cable in the top of the bore hole cover or man hole if one is available.
The cable is plastic and so is safe from corrosion.

Maintenance Procedures
Fibre Optic Header Unit
The Header units are robust and splash proof . The fibre optic port of the Header unit is a sealed device and is manufactured
from 316 or better stainless steel and under normal conditions is safe from corrosion and damage.
1,
Cleaning the fibre optic port.
Remove fibre termination cap by undoing the 4 x 2.5 mm bolts on the header units
Clean the fibre optic port by washing with de-ionised water, or if serious fowling use water with mild detergent.
and a cotton wool bud to remove any material. Allow plenty of time for the port to dry out before re-using the Header
for additional downloads.
The fibre port will operate even when wet as water ingress has little effect on the light transmission. Note there can
be signal attenuation when operating with water in the fibre port. For optimum results make sure the unit is dry.
2.
Replace the 2 X AA batteries fitted inside the Bluetooth Header unit typically after 500 downloads or
after excessive use. Should a sensor suddenly fail to operate then there is a good chance the batteries in the
Header unit needs replacing.
When the batteries are low then unusual behaviour of the status LED indicators may be observed.

Care of the Fibre Cable
The fibre cable should in fact be trouble free as it is safe from corrosion and cannot be damaged by lightening
strikes. Some wear and tear at the ends of the fibre where it is terminated into the AquaBAT and into the Header
unit is expected.
3.
After a successful deployment remove the bolts holding on the fibre termination cap from the AquaBAT take out the
fibre. Check the end of the fibre for wear and signs of stress damage due to the pressure asserted by the O-ring.
Should and stress damage be observed simply cut back the fibre and re-fasten onto the sensor. See details on
page 3.
Cut back the fibre as described on page 1 and re-attached the cable when necessary.
Care of the AquaBAT Logger Unit
After a successful deployment the AquaBAT should be cleaned before being re-used.
Make sure the Fibre termination cap is removed before cleaning.

Operating Environment
The AquaBAT will function satisfactorily in the worst of environmental conditions. The
instrument is of solid construction and does not use any vented signal cabling which is
the main point of weakness due to corrosion causing leaks for competitive products. For
inland water ways the AquaBAT is supplied in a stainless steel 316 or better casing.
For salt water applications a Titanium enclosure version instrument can be supplied.

Using a number of bore holes at widely spaced locations and the
ability of the AquaBAT to synchronise data by virtue of its use of its
temperature compensated clocks offer high stability. It is possible
to monitor the water table levels across defined land masses and
to get some indication that water flow is taking place by the change
in water temperature. The ability to take reading from a series of
locations enables the water table gradients to be followed through
the different perm abilities of the local ground conditions. With a
well planned and maintained water monitoring system effects on
the water table can be observed due to changes caused by local
building operations.

Measuring level
The AquaBAT determine the height of a water column above the sensor by measuring water pressure. A version of the
AquaBAT set to measure a range of 1 bar but calibrated to record barometric pressure is used available when local
barometric levels are required. The barometer version of the AquaBAT has part number AquaBAT-bar.
The AquaBAT is a very accurate device and can be setup to allow for local gravity, salinity and temperature. The sensor
automatically allows for varying temperature when taking a reading and storing data. The AquaBAT is an intelligent sensor
and as such can return water level data in a number of different engineering units. The output values from the AquaBAT
have to be in the same engineering units as the barometer for the optimum water level measurements to be achieved.
Typically both the AquaBAT level recorder and the AquaBAT-bar use units of mH20 for stored data.
The compensated water level values can be related to a reference point such as the top of the standpipe tubing at ground
level, or some other convenient reference level. To undertake this operation and in the event that the exact length of the
fibre cable being unknown, the distance between sensor head and the desired reference point needs to be measured and
can be manually entered into the Connect software during a download. Typically the initial water height as measured from
the top of the bore hole head using a water dip meter is used as the reference point.
Fibre-optic Cable
The water level measurement made using a dip meter is independent of barometric pressure and is an absolute
measurement. This makes it an ideal reference datum point.
Borehole Head
Datum
Barometer
The Reference Level used within this application is the distance
manually measured from a Datum level, normally the top of the
measuring tube to the water level obtained independently using a
water level meter (Dip-meter). The reference point establishes the
depth of the AquaBAT and allows readings of the AquaBAT to be
converted into readings referenced to the Datum level.
HDepth-to-water
If the elevation of the Datum level is established relative to national
datum ( Ordnance Datum or Port Datum) then water levels from other
wells can be compared related to a common datum.
It is necessary to record the time at which the Reference Point is
measured so that the AquaBAT reading can be used at the same time.
Water
Level
Reference
Level
HReading
HCable
An AquaBAT-bar barometric logger is used to measure the air pressure
variations for every measurement area. Typically only a single sensor is
needed for each 20 km2 area. Compensation for these air pressure
variations can be made quickly and efficiently using the Connect Logger
software package.
Sensor
Level
Example:
HDepth-to-water = Depth to water ( Reference Point) = 15.62 m
HReading = AquaBAT Reading = 10.52
Calculated depth of AquaBAT relative to Datum Level
= 15.62 + 10.52 = 26.10 m
This value of 26.10 is used to calculate Depth to water subsequently
e.g. AquaBAT reading = 5.10
Depth to water relative to Datum Level = 26.10-5.10 = 21.00 m
The Reference point should be re-established on a routine basis to ensure quality assurance by an independent means of the verification
of the data. Additionally, correct use of the Reference point will improve accuracy of readings, particularly at high pressure heads on the
AquaBAT.

Alarm Level Recording
The Alarm Level recording enables data to be acquired at a different rate to the standard data acquisition operation
when the water level exceeds pre-set conditions. When the Alarm Level data is recorded at a higher rate that the
normal data recording operations it allows the water level to be observed in greater detail and is ideal for pump tests
and monitoring flood conditions.
Alarm Conditions
The Alarm Level Recording is only active when both Low and high settings are defined.
Deeper Than (m)
- defines the level in m for which the water level must exceed before data is stored.
Shallower Than (m) - defines the minimum level that the water level must be less less than before data is recorded.
To activate Alarm Level Recording select the “Tick box” adjacent to the “Alarm”
menu option..

Synchronising the Internal Clock / Setting the Time Zone
The internal clock of the AquaBAT is very accurate and is temperature compensated.
Over time the clock can drift and may be reset by the User at any time.
By default the AquaBAT internal clock is set to GMT with no offset. Any offset due to operation in another time zone has to be applied to the instrument.
The following instructions demonstrate how to set the internal clock of the instrument.
1.
Ensure that the “Logging” Window is selected.
Press “Re-synchronise Clocks” button
The instrument clock will now be set to the clock of the PDA / Mobile Phone running the Connect software.
During the writing of any configuration information the instrument temporarily suspends the data logging
operations until the action is completed.
Adjusting the Time Zone
The Connect application software detects the internal time and date of the device running the software. Therefore
if a PDA / Mobile Phone is set to operate in a different time zone to the default setting of the instrument then the
new time will be uploaded upon selecting the “Re-synchronise Clocks” button.

Equations used to Determine Water Level
The following equations are used to correct the water level height for variation in Altitude, Temperature, Local changes in
Gravity and density of water.
Gravity Variations with latitude
Precise values of g (Gravity) vary depending on latitude on the Earth's surface. The standard acceleration due to gravity at
the Earth's surface is, by definition, 9.806650 m/s² (32.17405 ft/s²). This quantity is known variously as gn, ge (though this
sometimes means the normal equatorial value on Earth, 9.7803 m/s²), g0, gee, or simply g (which is also used for the
variable local value).
Pressure = . g .h
where
= Density Kg/m3
g = Gravity m/s2
h = Height of fluid column in m
How to determine local values of gravitational acceleration and altitude?
The variation in the value of g across the earth's surface is about 0.5 % due to latitude, plus a change of approximately
0.003 % reduction per 100 m altitude. Local topography and tidal forces also can have small effects.
An approximate value for g, at a given latitude and height above sea level, may be calculated from the formula:
g = 9.780 327 (1 + A sin2 L - B sin2 2L) - 3.086 × 10-6 × H m·s-2

Equatorial value gravity = 9.780327 m
Reference UK National Physical Laboratory
http://www.npl.co.uk/mass/faqs/gravity.html
The AquaSync software is preset to use ge = 9.780327 (Equatorial) value of gravity by default, however a more accurate reading can
be determined by adjusting the default value of g to suit the values shown at the locations in the table below.
If the sensor variation in altitude from the locations below is known then reduce the listed value by 0.003% per 100m increase in altitude.

Transient Protection
Why use Fibre Optic communications on buried sensors
Immunity to Microwave and RF radiation
Safe from lightning strikes by design
Corrosion proof design - Faraday cage Protection
No signal degradation with time
No electrical earth problems
Fast Installation - No need to hide cabling to protect communications and
power supply.
Simple Fibre Cable Installation - Only hex key and scissors required.
AquaBAT
The AquaBAT water level logger has advantages over any other similar devices or sensor
deployed using traditional copper wire for power supply and communications operations.
The advantages for using fibre optic plastic cable are:
Iso-voltage Levels
100 KV steps
Theory of Operation
Fibre Optic Cable
The drawing above shows the effect lightning hitting a
structure which is used to host instruments deployed
underground, or fitted into large structures using traditional
wire based communications and power supply arrangements.
Sensors deployed across a copper wire based network with
external power supply, can all be damaged by lightening or
the results made unusable by noise created by electromagnetic interference. Interference is often caused by mains
pickup or ignition noise from engines. When long runs of
copper cable are deployed they act as an antenna making the
cable very susceptible to this type of interference
Case forms
Faraday Cage
Why use Fibre Optic Communications
Faraday Cage
The enclosure surrounding the AquaBAT instrument
consists of a single solid piece construction body that when
completed with the top clinch plate forms a full conductive
path around the instrument. Any local potentiometric effects
caused by lighting strikes appears as the same voltage level
around the instrument and there is no chance for break
down as there is no potential difference. There is little
chance for damage to the instrument and no chance for
break-down of the fibre optic cable.
Fibre Optic Cable
The concentric lines shown in the above fibre represent
Iso-voltage levels at the instance of the lightening strike. Each
individual line represents a potential difference of 100 KV. A
cable that connects the instrument at the top of the bore hole
to the sensor at the bottom can in effect cross multiple
iso-voltage lines and so cause high voltages to appear across
the cable and sensor. These high voltages can break down
the cable isolation and destroy the sensor. Copper cable also
acts as a antenna and can very easily pick up local
electromagnetic interference and is a particularly difficult
problem to solve especially in long cable runs. There can be
no electro-magnetic pickup when using fibre optic cable.
Header
Unit
How to prevent damage
AquaBAT
Keynes controls prevent damage to the AquaBAT units by
using a solid fibre optic plastic cable for communication
and deployment. Plastic fibre does not conduct electricity
even if it takes a direct hit from lightening and therefore it can
never damage the logger unit.
